13 ib_acme provides assistance configuring and testing the ibacm service.
14 The first usage of the service will test that the ibacm is running and
15 operating correctly. The second usage model will automatically create
16 address and configuration files for the ibacm service.
17
19 -f addr_format
20 Specifies the format of the src_addr and dest_addr parameters.
21 Valid address formats are: 'i' ip address, 'n' host name, 'l'
22 lid, 'g' gid, and 'u' unspecified. If the -f option is omitted,
23 an unspecified address format is assumed. ib_acme will use
24 getaddrinfo or other mechanisms to determine which format the
25 address uses.
26 -s src_addr
28 Specifies the local source address of the path to resolve. The
29 source address can be an IP address, system network name, or
30 LID, as indicated by the addr_format option.
31 -d dest_addr
33 Specifies the destination address of the path to resolve. The
34 destination address can be an IP address, system network name,
35 or LID, as indicated by the addr_format option.
36 -v Indicates that the resolved path information should be verified
38 with the active IB SA. Use of the -v option provides a sanity
39 check that resolved path information is usable given the current
40 cluster configuration.
41 -c Instructs the ACM service to only returned information that cur‐
43 rently resides in its local cache.
44 -e [N] Displays one (N = 1, 2, ...) or all endpoints (N = 0 or not
46 present).
47 -P [opt]
49 Queries performance data from the destination service. Valid
50 options are: "col" for outputting combined data in column for‐
51 mat, "N" (N = 1, 2, ...) for outputting data for a specific
52 endpoint N, "all" for outputting data for all endpoints, and
53 "s" for outputting data for a specific endpoint with the address
54 given by the -s option.
55 -S svc_addr
57 Hostname, IPv4-address or Unix-domain socket of ACM service,
58 default: /run/ibacm.sock
59 -C repetitions
61 number of repetitions to perform resolution. Used to measure
62 performance of ACM cache lookups. Defaults to 1.
63 -A [addr_file]
65 With this option, the ib_acme utility automatically generates
66 the address configuration file ibacm_addr.cfg. The generated
67 file is constructed using the system host name.
68 -O [opt_file]
70 With this option, the ib_acme utility automatically generates
71 the option configuration file ibacm_opts.cfg. The generated
72 file is currently generated using static information.
73 -D dest_dir
75 Specify the destination directory for the output files.
76 -V Enables verbose output. When combined with -A or -O options,
78 ib_acme will display additional details, such as generated
79 address information saved to the ibacm_addr.cfg file.
80
82 The ib_acme utility performs two main functions. With the -A and -O
83 options, it automatically generates address or options configuration
84 files. The generated files are text based and may be edited. These
85 options are intended to provide a simple way to configure address and
86 option information on all nodes on a cluster.
87 The other function of the ib_acme utility is to test the ibacm service,
89 including helping to verify that the service is usable given the cur‐
90 rent cluster configuration. The ib_acme utility can resolve IP
91 addresses, network names, or IB LIDs into a path record. It can then
92 compare that path record against one obtained by the SA. When used to
93 test the ibacm service, the ib_acme utility has the side effect of
94 loading the ibacm caches.
95 Multiple, numerical destinations can be specified by adding brackets []
97 to the end of a base destination name or address. Users may specify a
98 list of numerical ranges inside the brackets using the following exam‐
99 ple as a guide: node[1-3,5,7-8]. This will result in testing node1,
100 node2, node3, node5, node7, and node8.
